[Incidence of peptic ulcers accompanied by gastrointestinal bleeding after surgery for critical lower limb ischemia]. / Vstrechaemost' erozivno-yazvennykh porazhenii zheludochno-kishechnogo trakta i krovotechenii u bol'nykh, operirovannykh na arteriyakh nizhnikh konechnostei po povodu kriticheskoi ishemii.

OBJECTIVE: To study the incidence of peptic ulcers accompanied by gastrointestinal bleeding after surgery for critical lower limb ischemia and their relationship with the factors predisposing to mucous membrane damage. MATERIAL AND METHODS: The study involved 94 patients with critical lower limb ischemia who were eligible for open bypass surgery. All patients underwent preoperative gastro- and duodenoscopy. The patients were followed up for 1 year, while the relationship between the nature of the lesion of the proximal gastrointestinal tract mucosa and the duration of pain syndrome against the background of ischemia, painkiller consumption and redo surgery. RESULTS: All study participants had lesions of the mucous membrane of the stomach and duodenum: inflammatory changes were identified in 92.6% of patients, ulcerative defects in 7.4%. When conducting a correlation analysis, we obtained a weak and moderate strength of the relationship between the duration of rest pain and severity of mucous membrane lesion and strong correlation between painkiller consumption and endoscopic data. Postoperative gastrointestinal bleeding was more common after redo reconstructive surgery or amputation compared to one intervention (7.7% and 1.8%, respectively). CONCLUSION: Various lesions of gastrointestinal mucous membrane are diagnosed in all patients with critical lower limb ischemia. It is associated with the underlying disease and painkiller consumption. Risk of bleeding is higher after redo surgery and amputations. Prevention of lesions requires comprehensive examination of patients and individual approach.

[Contemporary data on efficacy of anticoagulant therapy in recanalization of deep veins]. / Sovremennye dannye ob éffektivnosti antikoaguliantnoi terapii pri rekanalizatsii glubokikh ven.

The article is a literature review containing a detailed description of anticoagulant therapy variants, their efficacy in recanalization of deep veins, as well as patients' compliance to treatment. Russian specialists have demonstrated that the processes of active re-organization of thrombotic masses, in some cases leading to complete clearing of the vessel's lumen from a thrombus, may be observed at terms from 3 to 6 months, with a failure to occur within the above period reportedly followed by formation of irreversible cicatricial-sclerotic alterations in the veins. That is why adequate anticoagulant therapy should be initiated promptly in order to prevent the development of irreversible alterations and a decompensated form of chronic venous insufficiency. The process of recanalization of the venous segments involved appears to primarily depend on efficacy of anticoagulant therapy. Of special attention is a class of novel oral anticoagulants characterised by high clinical efficacy, prolonged and relatively safe administration, as well as thrombolytic activity. The use of anticoagulant therapy, as well as adherence of patients to treatment make it possible to significantly decrease the frequency of a decompensated form of venous insufficiency and the need for reconstruction of the major veins.

[The first episode of spontaneous pneumothorax (errors, hazards, complications)]. / Oshibki, opasnosti, oslozhneniia pri pervom épizode spontannogo pnevmotoraksa.

AIM: To analyze the errors and complications of surgical care in patients with the first episode of spontaneous pneumothorax at different hospitals. MATERIAL AND METHODS: From 2005 to 2015 three hundreds and seventeen patients with the first episode of spontaneous pneumothorax have been treated at the thoracic department of Volgograd State Medical University. Patients were divided into 2 groups: 79 of them underwent thoracotomy while in 238 cases minimally invasive technologies were applied. Faster preoperative management and earlier active surgical tactics were suggested. RESULTS: There were 6 the most typical violations of surgical care in 42% of patients with the first episode of spontaneous pneumothorax. Medical and diagnostic violations at regional centers and central district hospitals were the same, but there were differences in certain types of errors and their incidence. Minimally invasive technologies do not significantly affect the number of violations of thoracic surgery principles. Early procedures against the recurrence by using of thoracoscopic interventions reduce postoperative morbidity from 1.2 to 0.3% and mortality by 8.25 times.
